Hello everyone
I want to know the relation of THD with the output swing. I am working on OTA. I have a THD of -40dB which is bad. Now I have read on some search engine that:
1. To improve THD we have to check the swing.
2. But in different research articles its mentioned that the improvement of THD can be done by improving the Gm linearity. They have shown the graphs between Gm vs Vid for linearity.
Which point is right to improve linearity. Do I have to check the swing?
Thanks
